--- Comment #2 from guenter <guenter.k at arcor.de> ---
OpenSuse 12.3, latest updates as of 1.6.2014

 digikam --version
Qt: 4.8.4
KDE Development Platform: 4.13.0
digiKam: 4.0.0

There are three radio buttons for face detection:
*detect
*detect and recognize
*recognize

Only "detect and recognize" set crashes. Both other two go through.

KDE-Crash Reporter does not work at the moment, digikam disapears simply after
crash.

This is what gdb says on crash:

OpenCV Error: Bad argument (This LBPH model is not computed yet. Did you call
the train method?) in predict, file
